This year's honorees included music legend Bob Dylan, former Secretary of State Madeleine Albright, Pulitzer Prize-winning novelist Toni Morrison and former astronaut and U.S. Senator John Glenn, the first American to orbit the Earth.

"So many of these people are my heroes individually," the president told the "packed house" in the East Room of the White House. "I know how they impacted my life."

The president, who admitted to being a "really big fan" of Dylan's music, recalled being in college "listening to Bob Dylan and my world opening up because he captured something about this country that was so vital."

Dylan, wearing dark sunglasses and a bow tie, sat expressionless as the president spoke of the effect of his voice: "Its unique gravelly power was redefining, not just what music sounded like, but the message it carried and how it made people feel."

The president shared a similar connection with Toni Morrison, saying her prose "brings us that kind of moral and emotional intensity that few writers ever attempt."

"I remember reading 'Song of Solomon' when I was a kid and not just trying to figure out how to write, but also how to be and how to think," he said.

The Medal of Freedom recognizes "individuals who have made especially meritorious contributions to the security or national interests of the United States, to world peace, or to cultural or other significant public or private endeavors," according to the White House.

Dylan's "Like a Rolling Stone" and "Mr. Tambourine Man," Morrison's novels "Beloved" and "Jazz," and Albright's efforts to champion democracy and human rights across the globe were recognized as accomplishments worthy of this honor.

Other recipients today included retired Supreme Court Justice John Paul Stevens, civil rights advocate and labor leaders Dolores Huerta, and Pat Summitt, the "winningest" NCAA basketball coach who led the University of Tennessee's women's basketball team to more Final Four appearances than any other team, among others.

"Some of them are household names. Others have labored quietly out of the public eye. Most of them may never fully appreciate the difference they've made or the influence that they've had, but that's where our job comes in," the president said.

"It's our job to help let them know how extraordinary their impact has been on our lives. And so today we present this amazing group with one more accolade for a life well led, and that's the Presidential Medal of Freedom," he said.

Full list of recipients and their accomplishments, as described by the White House:

Madeleine Albright

From 1997 to 2001, under President William J. Clinton, Albright served as the 64th United States Secretary of State, the first woman to hold that position. During her tenure, she worked to enlarge NATO and helped lead the Alliance's campaign against terror and ethnic cleansing in the Balkans, pursued peace in the Middle East and Africa, sought to reduce the dangerous spread of nuclear weapons, and was a champion of democracy, human rights, and good governance across the globe. From 1993 to 1997, she was America's Permanent Representative to the United Nations. Since leaving office, she founded the Albright Stonebridge Group and Albright Capital Management, returned to teaching at Georgetown University, and authored five books.

In that capacity, he was instrumental during many major civil rights crises, including singlehandedly preventing a riot in Jackson, Mississippi, following the funeral of slain civil rights leader Medgar Evars in 1963. Doar brought notable civil rights cases, including obtaining convictions for the 1964 killings of three civil rights workers in Neshoba County, Mississippi, and leading the effort to enforce the right to vote and implement the Voting Rights Act of 1965. He later served as Special Counsel to the U.S. House Committee on the Judiciary as it investigated the Watergate scandal and considered articles of impeachment against President Nixon. Doar continues to practice law at Doar Rieck Kaley & Mack in New York.

Bob Dylan

One of the most influential American musicians of the 20th century, Dylan released his first album in 1962.

He helped shape the global health work of the Bill and Melinda Gates Foundation, and remains a champion of a wide array of issues, including child survival and development, injury prevention, and preventative medicine.

Gordon Hirabayashi

Hirabayashi openly defied the forced relocation and internment of Japanese Americans during World War II. As an undergraduate at the University of Washington, he refused the order to report for evacuation to an internment camp, instead turning himself in to the FBI to assert his belief that these practices were racially discriminatory. Consequently, he was convicted by a U.S. Federal District Court in Seattle of defying the exclusion order and violating curfew. Hirabayashi appealed his conviction all the way to the U.S. Supreme Court, which ruled against him in 1943. Following World War II and his time in prison, Hirabayashi obtained his doctoral degree in sociology and became a professor. In 1987, his conviction was overturned by the U.S. Court of Appeals for the Ninth Circuit. Hirabayashi died on January 2, 2012.

Huerta is a civil rights, workers, and women's advocate. With Cesar Chavez, she co-founded the National Farmworkers Association in 1962, which later became the United Farm Workers of America. Huerta has served as a community activist and a political organizer, and was influential in securing the passage of California's Agricultural Labor Relations Act of 1975, and disability insurance for farmworkers in California. In 2002, she founded the Dolores Huerta Foundation, an organization dedicated to developing community organizers and national leaders. In 1998, President Clinton awarded her the Eleanor Roosevelt Award for Human Rights.

Jan Karski

He worked as a courier, entering the Warsaw ghetto and the Nazi Izbica transit camp, where he saw first-hand the atrocities occurring under Nazi occupation. Karski later traveled to London to meet with the Polish government-in-exile and with British government officials. He subsequently traveled to the United States and met with President Roosevelt. Karski published Story of a Secret State, earned a Ph.D at Georgetown University, and became a professor at Georgetown's School of Foreign Service. Born in 1914, Karski became a U.S. citizen in 1954 and died in 2000.

Toni Morrison

One of our nation's most celebrated novelists, Morrison is renowned for works such as 'Song of Solomon,' 'Jazz,' and 'Beloved,' for which she won a Pulitzer Prize in 1988.
